Bad neighbor, good tenant in Milwaukee

[Don Jackson]

I have a property in Milwaukee with some good tenants. What I mean by that is they pay their rent on time and I get no maintenance problems. I thought everything was fine until I received a letter in the mail from one of the neighbors. I called this neighbor and she described to me the drug deals going on and the loud music in the cars that pull up to the house at all hours. She tells me that she called the property manager, but didn't get much in the way of warm and fuzzy feelings.

I assured her that I would look into it. Just what "look into it" means, I'm not really sure. I want to do right by the neighborhood. If my tenants are a nuisance I want to get rid of them.  Their lease goes until September. 

Is my best option to tell the property manager that I want these tenants out at the end of their lease?

I will cal the property manager on Monday. What should I say?

As an added note, Renters Warehouse is my PM. I'm not sure what kind of experience people have had with them.
